" claims.' (or. 24oitin This invention relates to new and useful im movements in a wire frame for lamp shades.

More speciiically, the invention proposes the construction of a wire frame for lamp shades 5 characterized by super-imposed frame members connected together by means of several tie rods in a manner so that a lamp shade cover may be rested against' the tie rods and upon a portion of the bottom frame member with its top edge engaging against a portion of the top frame member.

Still further it is proposed to characterize the frame members by vertically extended Wall portions upon `which the ends of the tie rods are connected and horizontally outwardly directed wall portions against which the edges of the lamp shade are adapted to engage.

Still further it is proposed to construct the lamp shade from parchment or similar material and to provide the same with a plurality of corrugations extending along its height and-into several of which the tie rods are adapted to engage.

Still further it is proposed to characaterize the outwardly extending horizontal wall portions of the frame members with holding elements for engaging over the edge portions of the lampy shade for holding the same in position thereon. Still further it is proposed toconstruot .the tie rods in such a manner that they may be held in a normal position with the edge portions of the lamp shade engaging against the adjacent face of the outwardly extended horizontal walls of the frame members and to permit the frame members to be moved -apart relativeV to each other for disengaging the same from the edges of the lamp shade to permit the lamp shade to be removed therefrom when desired.

For :further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the Fig. 2 is a perspective view of the wire frame per se. I

Fig. 11 is a view similar to-Fig. 10 but illustrating a shifted position of the parts.

The wire'frame forlamp shades includes va top framel member I@ having a vertical wall portion 'ida and an outwardly directed horizontalv wall portion illb continuing from the top of its vertical wallportion Ita. The top frame member is constructed from sheet metal or other similar material and is substantially L-shape in cross section as clearly shown in Fig. 3.

A bottom frame member I I has a vertical Wall portion II2L and an outwardlydirected horizontal wall portionIIb continuing from the bottom of its vertical wall portion Ila., This bottom frame member is constructed in a manner similar to the top frame member Ill and is also L-shape in cross section as shown inFig. 3.

Several'tie rods l2 are attached to and eX- tend between the vertical Wall portions Illa. The top ends of the tie rods l2 are securely attached to the vertical Walls Illa of the top frame member lll. This attachment is accomplished by welding, braizing, or in any other similar manner. The bottom ends of the tie rods I2 are securely attached to the vertical Wall portion I Iaof the b ottom frame member I I in a manner similar to that described relative to the attachment of the top ends to the vertical wall members Illa.

A lamp shade cover 4I3 is adapted to be rested against the tie rods I2 and upon the top face of the bottom horizontal wall portion I I and has its top edge engaged against the bottom face of the top horizontal wall Mib. The edge portions of the lamp shade I3 are adapted to engage the horizontal, wall `portions Vof the frames II) and I I for preventing relative movement between the lamp shade I3 and the wire frame. As clearly shown in Figs. 1 and 4 the lamp shade I3 is provided with a plurality of corrugations I3a extendview on the line Ill-'I0 of ing along its height and the tie rods I2 are adapted to extend into certain corrugations |38 permitting the lamp shade to pass there-around without in any way affecting the outer appearance thereof. The manner in which the corrugations extend around the rods I2 is clearly shown in Fig. 4.

If the lamp shade cover I3 should become soiled. or if it is desired to change the appearance of the lamp, the lamp shade cover may be removed from the wire frame to permit a lamp shade cover of different design to beengaged thereon. This removal is accomplished by spreading the top edge of the lamp shade cover I3 to permitl it to slip over the outer periphery of the top horizontally outwardly directedwall` portion; IIlb. When the lamp shade cover I3 is engaging over this outward periphery it may. be manually' bottom end thereof, is slipped over the top'frame'l II). and manually pressed downwards thereon to cause the edges thereof to be engaged between the outwardly directed horizontal wall portions IIib and IIb;

The wire frame is provided with a support means for permitting the shade to be engaged upon the bulb positioned within the socket of a conventional lamp. This support means com prises parallel piecesof Wire I4 having their ends securely attached to portions of the top frame member Il). Intermediate of their ends the wires I4 are formed with loop portions Ida which are adapted to engage'around the bulb` for supportn ing the wire frame upon the lamp. A ring I5 is engaged upon the wires I4 justabove the loops Ida for holding the loops in iixed position with relation to each other at their top ends in a man ner so thatthe bottom ends of thev loopsl I4# will be urged* apart to permitthem to be engaged over the bulb.

According to the modificationl of the invention shown in Fig. 5 the wire frame is constructed in a manner similar to that described relative to Figs. land 4, except that the top frame member I' is hexagonal in shape instead of circular. The bottom irarnemember I I' is also hexagonal in shape. Thetie rods I2 are extended between the frame members III and. II" andare securely attachedto the vertical wall portions IiiEL and I Ie thereof. In other respects this form ofthe invention is. similar to the previous form.

Accordingto the modification. shown inFig. 6 the-constructionof the wire frame-is similar to that described in connection with the previous forms of the invention except that the ends of the tierods I2 are securely attached to the. adn jacent faces of the horizontal.v Wall portions IIJband I Ib instead of the vertical wall portions Iii?- and Ile. In other respects thisform of the in* vention is similar to the previousforms.

According tothe modification of the invention shown in Figs. 'L11 inclusive the wire frames II] and Il are provided with a means for ene gaging the edge. portions oi the lamp shade cover I3 for securing the cover in position thereon. Still further this embodiment pro-vides a means for permitting the frame members III and II to be moved away from each other for releasing the holding action of the aforesaid' means for. penl mitting the lamp shade cover to be removed from the wire frame when so desired.

The means for holding the lamp shade comprises holding elements in the form of half circular extensions Ibb formed on the -o-uter edge of the horizontal wall I0" of the top frame member I0 for engaging over the top edge oi the lamp shade cover I3. The bottom horizontal wall IIb is formed with a similar half circular extension iIbb for engaging over the bottom edge portion of the lamp shade cover I3. The method in which these portions Ibb and I Ibb are adapted to engage the edge portions of the lamp shade cover I3 is clearly shown in Fig. 8 by the dot and dash lines I3.

The means for permitting-the frame; elements II! and II tothe moved away from each otherto release the holding action of the holding elements I!)bh andr IIbbcomprises several tie. rods I6 and. I1. attached to the vertical wall portions Illa and IIe. The tie rods I have their top ends securely' attached to the vertical wall portions 59a and the tie rods I'I have their bottom ends securely attached' to vertical wall portions II a. The tie rods I6 and I'! are normally in alignment l A socket member is mounted on. each of one oi the adjacent ends of the'tie rods. Asshown on the drawing, the socket members I8 are mounted upon the yends ofthe tie rods Il, and the ends of the tie rod It are adapted to extend into the hollow I8*L of the socket members 'Iii through an opening formed in the' top thereof. Adjacent the base wall of the hollow Ita in the socket III there is formed inwardly directed recess I9 and a similar recess 2D is formed above the recess I9 intermediate the `ends of the hollow IBR.

The bottom endsof the tiel rods It are formed with inwardly directed lugs I iia which are adapted to act in a manner for holding the frame menibers in a normal position or in a resiliently separated position from the normal. A. leaf spring ZI has one of its ends securely attached to the` Wall of the hollow I8a opposite the recesses I9 and 2t and is adapted to bear against the rods for urging these tie rods into a position in which the lug Ita maybe engaged into either of the` recesses I9 or'ZIl. Vvhen the lugs Ifia arsengaged into the lower recesses I9 the frame mem bers II) and II will be in their normal position in which the edge portions of the .lamp shade cover I 3 will be engaged between the adjacent faces of' the horizontal wall portions IIIb and IIb and beneath the holding elements Illbb and I Ibb.

' If. the lamp shade cover I3 becomes soiled or it is desired to changetheappearance of the lamp, the shade cover may be removed inthe followlng manner: The frame members Ii! and II are manually turned .with relation to each other to cause the tie rods I6 and. Il to move out of end alignment to disengage the lug II from the recess. I9. against the holding action of the spring 2I. The tie rods I6 may then lcepulledY out-- wards with relation to the socket members III to permit the lug I6ar to be aligned with the ro1 cesses 20. The top frame member is then released and the springs 2l willV cause the lug I8a to be seated into the recesses 2Il for holding the frames in. their extended position with relation to each other to permit the lamp shade cover I3 to be removed by'passingit over the top frame member I IJ. In other respects this form of the invention is similar to the previous forms.
